Abstract
This utility model provides a kind of polymeric film produced for Rigid Flex, including fender, base material and release silicon layer, sets gradually the first release silicon layer, the first base material, fender, the second base material and the second release silicon layer from the top down.The polymeric film stable in properties that the utility model proposes, it is adaptable to the process for pressing of Rigid Flex in circuit board.
Description
Technical field
This utility model belongs to microelectronic element production field, is specifically related to a kind of for circuit board
The film produced.
Background technology
Rigid Flex, it is simply that flexible circuit board and rigid wiring board, through operations such as pressings,
Combine by related process requirement, formation have concurrently FPC (flexible PCB) characteristic with
The wiring board of PCB (printed circuit board) characteristic.In Rigid Flex production process, need by
Multilayer material including PET (polyethylene terephthalate) base material and Copper Foil is superimposed on one
Rise, through process for pressing, then through laser boring (i.e. laser drilling), it is achieved between multilayer material
Be accurately positioned and turn on.
Production for Rigid Flex, it is desirable to have can with FPC, also can and PCB well tie
The PET multilayer film closed.
Utility model content
For solving the deficiency that prior art exists, the purpose of this utility model be propose a kind of for
The polymeric film that Rigid Flex produces.
For realizing this utility model purpose technical scheme it is:
A kind of for Rigid Flex produce polymeric film, it is characterised in that include fender,
Base material and release silicon layer, set gradually from the top down the first release silicon layer, the first base material,
Fender, the second base material and the second release silicon layer.
Preferably, described fender is polyethylene film (PO film).Polyethylene film softening point is little,
Be suitable to make the intermediate materials of Rigid Flex.The thickness of fender is 180～300 μm.
It is highly preferred that described polyethylene film or polyolefin film or polyolefin film.
Preferably, described first base material is the thin film of polyethylene terephthalate material, the
The thickness of one base material is 20～30 μm.
Wherein, described second base material is the thin film of polyethylene terephthalate material, second
The thickness of base material is 32～40 μm.
Wherein, the thickness of described first release silicon layer is 1～3 μm, described second release silicone oil
The thickness of layer is 1～3 μm.Described release silicone oil can use Dow corning 7362 silicone oil.
The beneficial effects of the utility model are:
PET film surface, can be obtained just topcoating cloth one leafing type silicone oil by coating process
There is the mould release membrance of release effect, then by middle superposition fender upper and lower superposition mould release membrance pressing
Together, can obtain release and buffering, filling effect three-in-one, further, at PET
Be coated with on thin film release silicone oil combine fender can be formed release and buffering, the three of filling effect
Unification.The polymeric film effect stability that the utility model proposes, it is adaptable to soft or hard knot in circuit board
The process for pressing of plywood.
Accompanying drawing explanation
Fig. 1 is the structure chart of this utility model polymeric film.
Fig. 2 is the process chart of polymeric film.
In figure, 1 is the first release silicon layer, and 2 is the first base material, and 3 is fender, and 4 are
Second base material, 5 is the second release silicon layer.
Detailed description of the invention
Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
In description of the present utility model, it should be noted that term " " center ", " ",
" laterally ", " on ", D score, "front", "rear", "left", "right", " perpendicular
Directly ", " level ", " top ", " end " " interior ", " outward " etc. instruction orientation or position
Relation of putting, for based on orientation shown in the drawings or position relationship, is for only for ease of this practicality of description
Novel and simplification describes rather than indicates or imply that the device of indication or element must have specific
Orientation, with specific azimuth configuration and operation, therefore it is not intended that to of the present utility model
Limit.
The release silicone oil used in embodiment is Dow corning 7362 silicone oil.
Embodiment 1:
See Fig. 1.A kind of polymeric film produced for Rigid Flex, the most successively
First release silicon layer the 1, first base material 2, fender the 3, second base material 4 and second are set
Release silicon layer 5.
In the present embodiment, described fender 3 is polyethylene film, and the thickness of cushion is 200 μm.
Polyethylene film good fluidity, it is easy to operation.First base material 2 is polyethylene terephthalate
The thin film of material, thickness is 25 μm.Second base material 4 is polyethylene terephthalate material
The thin film of matter, thickness is 36 μm.
Wherein, the thickness of described first release silicon layer 1 is 1 μm, described second release silicone oil
The thickness of layer 5 is 1 μm.
Preparation process such as Fig. 2.After release silicone oil is deployed, by machine in PET film through opening
Force system makes face tight smooth, then cross coating head coating, drying, tension system, cooling,
Compound composite membrane, rolling are shaped to three-in-one film.During coating, anilox roll and film trend are contrary,
For inverse painting, speed that anilox roll rotates and the speed ratio walking film are 105%, and silicone oil passes through reticulate pattern
Roller strap moves even spread and aluminium foil top layer, is fully cured through drying.Obtain is three-in-one release
Film, has release effect and high temperature resistant, keeps (180 DEG C without exception of 30min at 180 DEG C
* 30min) performance.
After having prepared three-in-one mould release membrance, after undue bar and section, form the lamellar of regulatory specifications
Then counterdie stacks, stacks fender, upper film stacks, pressing is fixed.Need smooth when stacking,
Non-wrinkle.Middle without air existence.Obtain the polymeric film produced for Rigid Flex.
Embodiment 2:
A kind of for Rigid Flex produce polymeric film, set gradually from the top down first from
Type silicon layer the 1, first base material 2, fender, the second base material and the second release silicon layer.
In the present embodiment, described fender is polypropylene screen, and the thickness of cushion is 220 μm.
Polypropylene screen good fluidity, figuration is effective, can cover at wiring board densely after the heating
Pit in.First base material 2 is the thin film of polyethylene terephthalate material, and thickness is
25μm.Second base material 4 is the thin film of polyethylene terephthalate material, and thickness is
38μm.Wherein, the thickness of described first release silicon layer is 1 μm, described second release silicon
The thickness of oil reservoir is 1 μm.
The preparation method of this polymeric film is with embodiment 1.
Above embodiment is only to be described preferred implementation of the present utility model, and
Non-scope of the present utility model is defined, before without departing from this utility model design spirit
Put, the various modification that technical scheme is made by this area ordinary skill technical staff
And improvement, all should fall in the protection domain that claims of the present utility model determine.
